SAMUEL LYON, OF PULTNEYVILLE, NEV YORK.

PARING AND CORING MACHINE.

SPECIFICATION forming part of Letters'Patent No. 409,111, dated August 13, 1889.

To all whom it mag/concern.-

Be it known that I, SAMUEL LYON, of Pultneyville, county of lVayne, and State of New York, have invented certain new and useful Improvements in Paring an d Ooring Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

My present invention relates to machines for paring and corin g apples or other similar fruit, and particularly to that class employing a turntable carrying a paring-knife adapted to revolve around the rotating fruit-fork, though.

some' of the parts could as well be applied to other forms of machines; and it consists in certain novel features of parts, all as will be hereinafter fully described, and the novel features pointed out in the claims at the end of the specification.

In the drawings, Figure 1 is a front elevation of a machine constructed in accordance with my invention ready for the paring op-- eration; Fig. 2, a similar view showing the location of the parts just before the paring operation is finished; Fig. 3, a top plan View of Fig. 1; Fig. 4, a vertical sectional view through the slide-operating mechanism when the operating-lever is in vertical position, moving the slide inward; Figs. 5 and 6,views of the'coring device and slide-supports. Fig. 7, a rear view' of the turn-table and knifearm; Fig. 8, a side view of the same; Fig. 9, a view ofthe fruit-deiiector, and Fig. 10 a view of a modification.

The main supporting-frame of the machine, constructed, preferably, of cast metal, is provided with laterallyA extended supportingfeet l 1, adapted to be secured to a suitable table or support, and between its two substantially upright end portions 2 2 are provided horizontal cross-bars 3, 4, and 5, the first mentioned at the bottom, the n ext d above it, and the last 5 constituting the' top, and extending beyond the forward standard is an overhanging portion 16, on which the turntable is supported, as will be described. This frame is preferably formed in one piece, and in it are also formed half-bearings in which Application filed January 21, 1889. Serial No. 297,021. (No model.)

operate the horizontal shaft G and the forkshaft 7, hcld in place by bearing-plates 8 8, bolted tothe frame, as shown, the former shaft 6 being provided at one end with alarge gear 9, to which is attached an operating-handle 10, and at the other with a small bevelpinion 11, meshing with the turn-table gear 12, support-ed in the overhanging portion of the main frame.

The fork-shaft 7, preferably of tubular form, is provided at its forward end with an ordinary fruit-fork 100 screwed upon it, and at its rear with a small pinion 141, meshing with gear 9, from which it receives motion, and operating within this shaft is a dofferrod 15, its end being adapted to project beyond the pinion 1a when the fruit is on the fork and to'be moved inward by suitable del vices when desired to eject the core. This particular arrangement of core-doffer is not essential to the operation of the doffer-operating devices hereinafter described, but is a desirable form.

Secured to the lower portion of the main 'frame is a iiat bar or plate of metal 17, ex-

tending out some distance parallel with the fork-shaft, and to the outer end is secured a casting 18, forming a guide for the slide carrying the coring-tube and actuating the fruitdoffer.

19 represents a bracket carrying the coring# tube 20, mounted upon a bar or plate 21,prefA erably flat, operating in guides in the casting 18 and main frame, said plate constituting a slide adapted to be reciprocaied at suitable times to cause thefcoring-tube to pass over the fork and separate the fruit from the core.

The lower portion of casting 18 is provided with a slight recess 22 in one face fitting over the bar 17, and a projecting portion 23, forining the bottom of the bearing for the bar 21. For the purpose of securing the casting to its support,and also of forming an adjustable bearing for bar 21, by means of which all lost motion and wear of the parts can be taken up, I provide a plate 24, slotted at opposite ends, and having a shoulder 25 near its upper portion secured to the casting by bolts 26 26, passing through the slots and entering the casting` The shoulder 25 bears on the top of the bar 21 and prevents all vertical move- IOO ment, while the plate and casting form its guides, the lower end of the plate projecting over bar 1'7 and securely clamping it to the casting. All wear can be readily taken up by moving this plate down and securing it in position by means of the screws, and in order to prevent all liability of the plate becoming displaced during this adjustment, and to hold it securely in position I provide small lugs 27 27 on the casting, arranged to enterthe slots, as will be understood.

The guide for the inner portion of the bar 2l is formed by a plate similar to plate 2i, a support for said bar being formed by a depending arm secured thereto, and operating on a way, farther on described, and the lower end of plate 2l projects over bar 17, though this is not essential, as the latter is bolted to the frame near thispoint. The bracket 19 is composed of two parts bolted to the bar 2l, each part being provided with recesses, and grasping the tube between them, as shown, and above the tube each has a lug 2S, the two forming a guide in which rests the fruit-doffcr rod 29, the outer end being adapted to strike againstcasting 1S when the slide is moved outward, and the inner end formed with or connected to acollar 230, sliding o n the tube and adapted, when the rod is held sta.- tionary and the tube is moved, to push olf the fruit.

For the purpose of delivering the pared fruit or the parings, or both, at either the front or the rear of the machine, I provide anincline or chute 3l constructed, preferably, of sheet metal and having on its under side arms 32, preferably, also, of a single piece of sheet metal, and adapted, when in position, to clasp the sides of the bar 2l. and hold the chute direct-ly beneath the end of the tube, so that as the fruit drops oft it will be caused to pass in front or rear of the bar, as may be desired, depending on the direction in which it is inclined. It will be understood that this chute can be reversed or removed entirely, if desired, the spring-arms grasping the slide facilitating this. As a means for operating this slide, though equally well adapted for moving any kind of a slide or carriage in a machine of this general description, I prefer to construct the parts as follows: Mounted upon the main frame and secured to the upper and middle cross-bars is an upright bar or casting 33, having a stud or pin 35 projects ing from its front, on which is mounted a large bevel gear\vheel .36, rotated in the direction of the arrow, Fig. l, by a bevel-pinion 37 on the shaft t'. Near thelower end of this bar is provided a projection or boss $34, hav ing a reduced portion on its outer end, on which is pivoted a lever 3S), the latter being held a suilicientdistance in front of the gear 36 to permit its free operation. The upper end of this lever is provided with a slot 40, in which operates a f riction-roller tl, mounted on wrist-pin 42, formed upon or secured to the gear 3U, the connection being such that upon the rotation of the gear the lever will be vibrated on its pivot, and to thelower end is pivoted a cross-head 47, having slots 4G t6 in its ends, as shown. To the inner end of the bar 2l is secured a depending arm 96, forming a support for the same, having at its lower end a flange or shoe 97, arranged to bear against the top and outer face of a plate 43 on the main frame, and on this arm are provided two pins 4l Lil, having friction-rollers 45 thereon, adapted to operate in the slots Ul in the cross-head. I prefer to support the inner end of the bar 21 upon the plate 43 through arm 9G, instead of directly underneath the plate 2l on the frame, as its bearing-points will be thus further removed fi'om the fork, and the liability of gunnning and unusual wear from the fruit-juice on a supportingsurface will be lessened. The projection Q5 on plate 2l! bears on the top of the slide and holds it down on the way 43, and'any wear at this point can be taken up by adjusting the said plate. XVhcn the gear-3U is rotated, the pin l2 causes the lever 2l!) to be vibrated in opposite directions on its pivot, moving the slide through the parts just described, and it will be noted that in the rotation of gear 36 the pin l? will operate in the lower portion of the slot 40, near the pivot of the lever, when causing the outward movement ol. the slide, moving it quickly at this time, but as the outer end of the lever is acted upon when the slide is moved in the coring operationu will be accomplished more slowly, the point ol' connection being farther from the pivot.

, In the operationv of the slide by the crosshead- 47, it will be noted, the latteris given a vertical movement, by reason of the end of leverf) moving in the are of a circle, thus insuring a more even motion with less liability of binding than would be the case were the end of the lever slotted to operate directly on the cross-bar 9G, though this latter construction could be employed in some instances, if desired.

Iivoted to the main frame, or in the present instance to the end of bar i7, is a lever 4S, its upper end being adapted at propel' times to operate upon the end ol' the coredolfer rod 11.5, and to it is pivoted a latch or link 19, its free end extending over the boss 38 on the bar 33, or a suitable projection on the main frame and normally supported thereon, a hook or projection 5t) being formed on its end to engage said boss 3S and prevent its moving too far to the right, and the lower side of the latch being further provided with a projection 5l, preferably beveled slightly on the left-hand side, willi which engages a projection 5i' on the bar 2l in the shape of a bracket secured to the crossbar OG. When the doffer is jnojceted to the right by impaling an apple on the fork, the dolli'er and its lever are moved out, and the end of the link jt-) is supported on the boss SES, and as the slide is moved to the right the projection 5l lifts the link and passes back of the projec- IOO IlO

tion 52; but when the slide moves in the opposite direction theprojections 51 and 52 engage and the link and lever are carried with it, projecting the doffer-rod and removing the core from the fork. The link slides up on the boss 3S until the projections 51 and 52 are disengaged, when the doffer and lever caribe returned to their first position by placing another apple on the fork, as will be understood. The turn-table, supported in the overhan gin g portion 16 of the main frame, consists of a gear-wheel 12 (preferably recessed at 55 on its upper side and arranged to be rotated from pinion 11) upon a bolt or stud 56 on the frame. position and facilitating the construction of the cam for operating` the knife-arm, I cast the overhanging portion 16 with a half-bearing on its front side for the accommodation of bolt 56 and a segmental flange 57 on its rear side, and provide a casting 59, bolted to the portion 16, having a recessed upper part for the bolt 56 and a lower iiange 60, which latter, with the flange 57, constitutes the semicircular cam for lifting the knife-arm over the fork-shaft when the turn-table is rotated. The head of the bolt 56 engages the under side of the gear-wheel 12, and the bolt is held in position by a nut 62 screwed on its upper end, being prevented from rotation by a setscrew passing through casting 59 and engaging its side, or any other suitable device for the purpose could be employed, if desired.

The gear-wheel 12 is provided with a perforation 63 for the passage of the knife-arm 64, which latter is constructed with laterallyprojecting arms or trunnions 65 65, having their bearings in recesses 66 66 in the upper side vof plate 67, the latter being bolted to the under side of the gear-wheel, said plate being further provided with av slot 68 for the knifearm, the end of said slot serving as a stop for limiting its inward movement, caused by a spring 69, connected at one end to the knifehead 70 on the arm and at the other to a pin 71, secured in one ofa series of perforations 72 in a flange 7 3 on the plate. The knife-head 70 is provided at its lower portion with a perforation for the parings, a paringknife 74, and guard 75, as usual, and on its rear side with a perforated lug 7 6,in which the end of. the knife-arm projects, the upper portion partially encircling the arm and having a slot 77, through which. passes a screw 7 8, the latter entering' the arm and serving to limit the rotary motion of the head thereon: By connecting the spring 69 to the movable knife-head and providing a series of points of connection between the latter and the knife-arm support the knife not only is held pressed against lthe fruit and the head permitted a slight independent oscillating motion, thus allowing1 it to follow more accurately the inequalities of the fruit-surface, but by changing the point of connection between the spring and turn-table and the direction of the pull of thespring, the .angle at As a means for securing this bolt inwhich the knife strikes the fruit or leaves it can be changed, as may be desirable or necessary in order to pare the Afruit at the ends in a more perfect manner, this adjustment depending upon the variety of fruit being operated upon.

The motion of the knife-arm toward the center of the turn-table, as stated, is normally limited by the end of the slot 68, and as a means for regulating this movement, so that if large fruit alone is to be pared the arm will be held fart-her from the fork, I in some instances employ a small wedge 79, secured to the arm by a screw 80, or otherwise, which, wh en in position, comes into contact with the end of slot 68, and may be moved up or down to determine the normal position of the knife relative to the fork, as shown in Fig. 10.

The bolt on which the turn-table rotates is preferably set at a slight angle to the plane of the fruit-fork, the center being preferably forward of the latter, as the knife only operates upon one side of the fruit when paring and moves in a semicircle, being lifted over the fork-shaft and carried to the rear and away from the fork by the cam-surface, over which the end of the knife-arm moves.

When the machine is in the position indicated in Fig. 1, it is ready for operation, the

'slide carrying the coring-tube being at the eXtreme left and the knife-armbeing swung back out of the way and against the tension of the spring, its upper end being confined under the cam 57 60. The operator now impales an apple upon the fruit-fork, pushing the doffer-rod 15 and its operating-lever out at the right, and then grasping the handle rotates the wheel 9, causing the rotation of the turntable, the sliding of the coring-tube slide inward, and the rapid rotation' of the forkshaft.

As soon as the turn-table rotates sufficientlyto release the upper end of the knife-arm from the cam its spring draws the knife down against the end of the fruit, which, being r0- tated rapidly, causes the skin to be removed, and the independent movement permitted the head allows it to follow the inequalities of the fruit more readily. NVhen a half-revolution of the turn-table has been made and the knife has reached the stem end of the fruit, the upper end of the knife-arm strikes the forward portion of the cam and turns the arm on its pivots 65 65, raising the knife-head above the fork, and the continued movement of the turn-table carries the head around to the first position, being still held away from the fork by the cam. 'By thus holding the knife-head away from the fork at all times, save during the paring operation, the operator is enabled to place the fruit on the fork without danger of his hand striking the knife.

During the paring operation the wheel 36 is of course being rotated from shaft 6, and the pin 42 causes the oscillation of the lever 39 and reciprocation of the coring-tube, which latter enters the fruit about the time the IOO knife is operating on the middle portion and severs the core just after the knife leaves the fruit. This inward motion of the tube, being caused by the operation of the pin 42 in the upper end of the slet in lever 3), is consequently slow; but when the pin operates the opposite side of the slot to return the slide to outer position, as it is operating close to the pivot of the lever, it will move faster and carry the slide outward rapidly. As the coring-tube slide is moving inward, the projection 52 on bar 2l slides up the incline on the latch I9, and, lifting the latter, becomes engaged with the projection 5l. Then as the carriage begins to move outward the latch is drawn with it, moving the core-(iOffer rod and causing the core to be pushed off the fork and into the coring-tube, the latch being released from the projection 52 at the proper time by riding up on the projection on the frame-in the present instance formed by boss 38.

J ust before the cori 11g-slide reaches its outermostposition the end of the fruit-dottor 29 strikes the casting 1S, sliding the dottor-sleeve outward and pushing the fruit which is sup ported on the tube oil?, when it is received upon the chute 3l and delivered at one side or the other of the machine, as may be de sired.

When the machine resumes the position shown in Fig. l and another apple is placed upon the fork, the operation just described is repeated, and so on indefinitely.

The employment of the bar 17 and the casting 1S materially cheapens the cost and lightens the forward part of the machine, while the slide-bar 2l, carrying the coring-tube, being guided in bearings at opposite ends, is steadied and its proper operation insured.

This machine is very simple in construction, is easily and cheaply made, and, as I have found in practice, is admirably adapted for the purpose, paring` and coring the fruit without unnecessary waste.
